Please help I I decided to screen shot something in my laptop but now my screen isn’t working or moving can you give me a way to solve my problem this is for 24 points

//import the Scanner class to allow for user input

import java.util.Scanner;

//Begin class definition

public class FirstAndLast{

   //Begin the main method

    public static void main(String []args){

       //****create an object of the Scanner class.

       //Call the object 'input' to receive user's input

       //from the console.

       Scanner input = new Scanner(System.in);

       //****create a prompt to tell the user what to do.

       System.out.println("Enter the string");

       //****receive the user's input

       //And store it in a String variable called 'str'

       String str =  input.next();

       //****get and print the first character.

       //substring(0, 1) - means get all the characters starting

       //from the lower bound (index 0) up to, but not including the upper

       //bound(index 1).

       //That technically means the first character.

       System.out.print(str.substring(0,1));

       //****get and print the last character

       //1. str.length() will return the number of character in the string 'str'.

       //This is also the length of the string

       //2. substring(str.length() - 1) - means get all the characters starting

       // from index that is one less than the length of the string to the last

       // index (since an upper bound is not specified).

       // This technically means the last character.

       System.out.print(str.substring(str.length()-1));

    }  // end of main method

} //end of class definition

Answer:

Un cursograma permite representar gráficamente procedimientos administrativos. Constituyen instrumentos importantes para la visualización global y esquemática del conjunto de tareas administrativas.

Answer:

The procedure in python 3 is as follows:

def add_range(low,high):

   if low<= high:

       total = 0

       for i in range(low,high+1):

           total+=i

       return total

   else:

       return "Failure"

Explanation:

This defines the function/procedure

def add_range(low,high):

If low is less or equal to high

   if low<= high:

Initialize total to 0

       total = 0

Add up numbers in the range

       for i in range(low,high+1):

           total+=i

Return the total

       return total

If low is greater, then return failure

   else:

       return "Failure"

Answer:

For the mean, do the following:

mean = sum/limit;

cout<<"Mean: "<<mean;

For the median do the following:

for(int i = 0; i<limit; i++) {

  for(int j = i+1; j<limit; j++){

     if(householdSizes[j] < householdSizes[i]){

        temp = householdSizes[i];

        householdSizes[i] = householdSizes[j];

        householdSizes[j] = temp;       }    } }

median= (householdSizes[(limit-1)/2]+householdSizes[1+(limit-1)/2])/2.0;

if((limit - 1)%2==0){

   median = householdSizes[limit/2];

}

cout<<endl<<"Median: "<<median;

Explanation:

The bubble sort algorithm in your program is not well implemented;

So, I replaced the one in your program with another.

Also, some variable declarations were removed (as they were no longer needed) --- See attachment for complete program

Calculate mean

mean = sum/limit;

Print mean

cout<<"Mean: "<<mean;

Iterate through each element

for(int i = 0; i<limit; i++) {

Iterate through every other elements forward

  for(int j = i+1; j<limit; j++){

Compare both elements

     if(householdSizes[j] < householdSizes[i]){

Reposition the elements if not properly sorted

        temp = householdSizes[i];

        householdSizes[i] = householdSizes[j];

        householdSizes[j] = temp;       }    } }

Calculate the median for even elements

median= (householdSizes[(limit-1)/2]+householdSizes[1+(limit-1)/2])/2.0;

Calculate the median for odd elements

if((limit - 1)%2==0){

   median = householdSizes[limit/2];

}

Print median

cout<<endl<<"Median: "<<median;

Answer:

Following are the response to the given question:

Explanation:

They are already talking business to business collects in which we are calling the client for collecting whenever the products which we have purchased are overdue and overdue inside 30 days. About business criteria, we should ensure no other websites mostly on agent acting open up so that nobody can misuse it; we also have to know the correct revising and trying to run off all systems and therefore all apps are organ systems because then the critical business work time has would not get out of the way. This is about the security of information. The agents also are adequately taught in IT policy according to the demand of the company.

They soon come towards the area of risk, experience, and skill. All agents ought to have proper refresh sessions to fulfill GAP knowledge but also improve their abilities for 100 percent cent accuracy on TAT on every appeal. Your Agency's response.

There ought to be a right party connect. We must keep up with 80-20 RULE which means that we can easily acquire the bigger amount earlier than somehow investing whatever money for future production if we concentrate on TOP 20 Overdue Current Passengers.

When we add up the current sum owing as well as the amount due by both the end of the month, so we will subtract all promises that were made by the end of each month. You can readily deduce how long and how much money will be received by the end of each month, and how long this will be due by the end of each month.

The total danger which we imagine to be cash flow issues is when a company is close to collapse or even has a money problem, they are few risks that any company has.

To solve this RISK to money flow clients, we have to provide them a payment plan so that we could at the very least invest some cash in additional production. Besides offering customers a pay system, you truly cannot help.

Another key potential risk is the unrequired quantity on the accounts of the consumer. Underneath the U.S. government, it'll be a direct responsibility of the government if there is an unclear and unapplied amount which has lied to an account for even more than 4 years.

Therefore it does have to do about risk, skills, knowledge the safety of information. All above theory helps explain everything which enables the execution of operations as well as, as project manager, we have to track input and output information. we need to charge, past due, credits, debits, PD percent every week and month, seeing the company's pattern, and also transform policies as to how the trend or even the forecast can enhance.

Answer:

The code is not dereferencing the pointers. You have to place an asterisk in front of the pointer to read the value the pointer points to.

Explanation:

So "if (str1 != str2)" must be "if (*str1 != *str2)".

likewise:

   while (*str1 != 0 && *str2 != 0)

and

     result = (*str1 == *str2);

Answer:

The function in python is as follows:

This returns twice of num

   return 2 * num

Answer:

The program in C++ is as follows:

#include <iostream>

using namespace std;

int main(){

   int questions, answer;

   cout<<"Questions: ";

   cin>>questions;

   int answerkey[questions];

   cout<<"Enter answer keys: ";

   for(int i = 0; i< questions; i++){

       cin>>answerkey[i];    }

   int correct = 0;

   cout<<"Enter answers: ";

   for(int i = 0; i< questions; i++){

       cin>>answer;

       if(answer == answerkey[i]){

           correct++;        }    }

   cout<<"Correct answers: "<<correct<<endl;

   cout<<"Percentage correct : "<<(100 * correct)/questions<<"%";

   return 0;

}

Explanation:

This declares the number of questions and the answers submitted to each equation

   int questions, answer;

Prompt to get the number of questions

   cout<<"Questions: ";

This gets input for the number of questions

   cin>>questions;

This declares the answerkey as an array

   int answerkey[questions];

Prompt to get the answer key

   cout<<"Enter answer keys: ";

This iteration gets the answer key for each question

   for(int i = 0; i< questions; i++){

       cin>>answerkey[i];    }

This initializes the number of correct answers to 0

   int correct = 0;

Prompt to get the enter the answers

   cout<<"Enter answers: ";

This iterates through the answer keys

   for(int i = 0; i< questions; i++){

This gets the answer to each question

       cin>>answer;

This compares the answer to the answer key of the question

       if(answer == answerkey[i]){

If they are the same, correct is incremented by 1

           correct++;        }    }

Print the number of correct answers

   cout<<"Correct answers: "<<correct<<endl;

Print the percentage of correct answers

   cout<<"Percentage correct : "<<(100 * correct)/questions<<"%";

Answer:

The recursion function is as follows:

def raise_to_power(num, power):

if power == 0:

 return 1

elif power == 1:

 return num

else:

 return (num*raise_to_power(num, power-1))

Explanation:

This defines the function

def raise_to_power(num, power):

If power is 0, this returns 1

if power == 0:

 return 1

If power is 1, this returns num

elif power == 1:

 return num

If otherwise, it calculates the power recursively

else:

 return (num*raise_to_power(num, power-1))

Explanation:

Given the following data;

Resistance = 30 Ohms

Voltage = 240 Volts

To find power rating of the kettle;

Mathematically, the power consumption of an electric device is given by the formula;

Power = voltage²/resistance

Substituting into the formula, we have;

Power = 240²/30

Power = 57600/30

Power = 1920 Watts or 1.92 Kilowatts

Answer:

Spelling

Word processors contain an electronic spell checker. The student writer has immediate feedback about misspelled words. Student must discern which of the computer-generated spellings is correct for the context. Teachers no longer have to red-ink spelling errors. They can focus on the few exceptions the spellchecker does not catch.

Security

Teachers and students gain a sense of security about losing assignments. When the student saves her work, she avoids the possibility of the assignment being lost or misplaced. If an assignment is ever misplaced, a replacement can be easily printed.

Legibility

Teachers benefit by receiving a readable copy that is easy to grade. Students with poor handwriting can increase their scores with better looking papers. Students should be instructed to turn in copies of work in a readable font.

Publishing

Work done on a word processor can easily published on a bulletin board. Teachers can create electronic anthologies of their students' writings. Each student can receive an electronic copy of published works with no printing costs.

Mobility

Work done on a word processor and saved on the Internet is highly portable and accessible from any computer with Internet access. Dogs do not eat papers in cyberspace. "I forgot it at home" is irrelevant. Just log onto the nearest computer and your work appears on the screen.
